Flagging as an anomaly even though no algorithms failed

[hughmann-dg]

Just started testing out skyline and I started seeing today that skyline was flagging one of my metrics as an anomaly even though none of the algorithms failed. See highlighted below. I did have the CONSENSUS = 1 just increase the sensitivity. Any ideas on why this is happening?

Found the issue. median_absolute_deviation was not setting the return if the test passed. This was causing run_selected_algorithm to view it as != False. I fixed it in my fork:
